So I'm a bad guy.

Do you get violent urges?

I doubt this, because it is true what they say: if you were a "bad" person, you wouldn't be bothered by it.

Were you less mean when you had this belief?

0.) Be happy. This is pretty much guaranteed to make you benevolent to others, if you have morals.

1.) Get the fuck out of customer service. If you have certain tendencies toward being mean, putting up with shit from people who think of you as less than human will not help. You might be being a dick as a defense mechanism, to preempt those that have abused you in customer service before.

2.) The way you act without premeditation is a result of core beliefs you have. You mentioned earlier that you assumed that most people were good and decent. Believing the worst about people will easily make you a grouch. Examine how you changed when your beliefs about people changed.

3.) If this is the case, simply change your beliefs. Make a conscious effort to look for examples of people doing good. There are several books and websites dedicated to counterbalancing the current negativity in the media. Fuck, you could even read some of those Chicken Soup for the Soul books.

Then you're probably not a sociopath, as much of an advantage that would be to you. Sucks to be you, sir. You're in an uncomfortable spot right now. You've realized that people can be nasty, especially to people they consider beneath them, and you've lost faith in humanity. You can either take the next step on the road you seem to be on and attempt to become a sociopath, or you can bury your head in the sand, only choose to look at the good examples of human behavior, and have unjustified faith in the better aspects of humanity. (Okay, so I'm a little biased.)

Jam it back in, in the dark.
